Hey James,
There is actual software that you can use to slow the instruments so you can pick out the notes more easily.
There is also an app that does this called Anytune that is five star rated.
Also, there are many well known tunes that Ben is going to add, and I’m pretty sure I’ll Fly Away is one of them. (License negotiations pending).
Yesterday was the first time I heard this version, and I really loved that part at 1:18. I think if you can crack the first four or five notes, you can take it right down the neck and back up. That’s just my guess though.
Wishing you the best with your banjo.
Jack
